(A) Isc baseline and (B) TER measurements of jejunal segments from OVA-sensitized mice following Vehicle (Saline) or OVA oral challenge (7th challenge) and stratified according to secretory diarrhea development (60 min). OVA-sensitized mice were challenged with OVA (7th Challenge) and evidence of profuse liquid stool (diarrhea-positive) was examined. Following the 60 min diarrhea observation period, jejunal segments were removed and mounted in a Ussing Chamber system and Isc and TER were recorded as described in the Material and Methods section. Data are represented as the mean ± SD, n= 4 - 7 mice per group. **** P < 0.0001, *** P < 0.001, ** P < 0.01, * P < 0.05, ns > 0.05.
